     --tool-arg limit=5
   
   # Get specific issue details
   npx @modelcontextprotocol/inspector --cli \
     -e REDMINE_API_KEY=$REDMINE_API_KEY \
     -e REDMINE_HOST=$REDMINE_HOST \
     node dist/index.js \
     --method tools/call \
     --tool-name get_issue \
     --tool-arg id=1
   
   # Filter issues by project
   npx @modelcontextprotocol/inspector --cli \
     -e REDMINE_API_KEY=$REDMINE_API_KEY \
     -e REDMINE_HOST=$REDMINE_HOST \
     node dist/index.js \
     --method tools/call \
     --tool-name list_issues \
     --tool-arg project_id=1 \
     --tool-arg limit=3

3. Test Projects functionality:

   # List all projects
   npx @modelcontextprotocol/inspector --cli \
     -e REDMINE_API_KEY=$REDMINE_API_KEY \
     -e REDMINE_HOST=$REDMINE_HOST \
     node dist/index.js \
     --method tools/call \

  -e REDMINE_API_KEY=$REDMINE_API_KEY \
  -e REDMINE_HOST=$REDMINE_HOST \
  node dist/index.js \
  --method tools/call \
  --tool-name list_issues \
  --tool-arg subject="bug" \
  --tool-arg limit=3

# Get time entries for specific project
npx @modelcontextprotocol/inspector --cli \
  -e REDMINE_API_KEY=$REDMINE_API_KEY \
  -e REDMINE_HOST=$REDMINE_HOST \
  node dist/index.js \
  --method tools/call \
  --tool-name list_time_entries \
  --tool-arg project_id=1 \
  --tool-arg limit=10

Troubleshooting:

• Connection issues: Verify your Redmine server is running and accessible:

  curl -H "X-Redmine-API-Key: $REDMINE_API_KEY" \
       "$REDMINE_HOST/projects.json"

• Permission errors: Some operations require administrator privileges. Check your API key permissions in Redmine.

• Environment variables: Ensure environment variables are properly set:

  echo $REDMINE_API_KEY
  echo $REDMINE_HOST

• Build issues: Make sure the project is built and permissions are set:

  npm run build
  chmod +x dist/index.js
  ls -la dist/index.js

Permissions

Some features require administrator privileges:

User-Related Operations

• list_users: Admin required

• update_user: Admin required
• delete_user: Admin required

Available information varies based on user permission levels. For details, see Redmine API Documentation.
